The Beta 250 RR 2-Stroke is a light and agile off roader powered by a Beta-built, single cylinder, 2-stroke, liquid cooled engine with BPV power valve system and electric start with back up kick starter. The engine is combined with a six speed transmission and is mounted on a molybdenum steel/double cradle frame.

To be able to deal without problems with a wide range of terrains, the Beta 250 RR 2-Stroke needed a set of capable suspensions, therefore the motorcycle rides on front a 48 Mm Sachs USD Fork and a rear aluminum Body Sachs Shock.

Among the new features available for the 2015 model year you will find, new CDI mapping, new front fork compression piston, a handlebar pad from Race Edition and a fresh seat as well as new graphics and color scheme.

The Beta 250 EE 2-Stroke is available with a base price of $8,199.

The main objectives during development were to make the bike lighter, easier to control, and improve overall handling making it more enjoyable and easier to ride and, above all, more effective. The engine’s center cases and internal components have been made lighter and redesigned to reduce the rotating mass, and the engine sizes have been reduced to make handling easier and minimize weight. Compared with the larger capacity of the previous model, the absolute power and torque figures remain unchanged thanks to a new camshaft profile and a new exhaust system; in addition, a better distribution of the torque curve has been obtained to get more out of the engines. With these new engines, the engineering team promises continued "Beta Magic" power delivery.

Quotes:

“The 2015 RR Enduro 2-stroke range has also evolved, the 250 version featuring certain technical innovations and the 300 version featuring special parts from the 2014 Racing model.”

“The objective here is to increase the smoothness and improving power from the bottom to the top end making the "right" power available to the rider at all times and under any condition.” — Total Motorcycle

“The 250RR and 300RR 2-Strokes get some engine love as well. For the 300, Beta transferred its 2014 RR Race Edition mill with a new cylinder, combustion chamber and CDI. On the 250, the company updated the engine’s exhaust valve adjustment system and fitted a new silencer to the pipe.”

“Both 2-Strokes benefit from the same suspension upgrades as the RS and RR models, with matching tweaks to the Sachs fork and rear shock.” — Motorcycle USA
